Is there a limit to how many (quantity or amount) apple gift cards I can add to my Apple Pay account?

Hey Nedfromia,

Thanks for posting your question in Apple Support Communities!

Currently there is not a limit to the amount of gift cards that you can add to your account. When you upload a card it goes directly to your account's overall balance and as for the amount of cards there isn't a limit. There is, however a limit for the maximum credit that can be added to the balance which is $20,000USD but can vary depending on your country or region.

You can find the specific account balance limit for your region by following this link: Apple Cash and person to person payments limits

Best Wishes.
